Commuting is periodically recurring travel between one's place of residence and place of work, or study, and in doing so exceed the boundary of their residential community.[1] It sometimes refers to any regular or often repeated traveling between locations, even when not work-related. A distinction is also often made between commuters who commute daily or weekly between their residence to work place, and are therefore considered respectively local or long-distance commuters.

The word commuter derives from early days of rail travel in US cities such as New York, Philadelphia, Boston and Chicago, where, in the 1840s, the railways engendered suburbs from which travellers paying a reduced or 'commuted' fare into the city. Later, the back formations "commute" and "commuter" were coined therefrom. Commuted tickets would usually allow the traveller to repeat the same journey as often as they liked during the period of validity: normally, the longer the period the cheaper the cost per day.[2]

Before the 19th century, most workers lived less than an hour's walk from their work. Today, many people travel daily to work a long way from their own towns, cities, and villages, especially in industrialised societies. Depending on factors such as the high cost of housing in city centres, lack of public transit, and traffic congestion, modes of travel may include automobiles, motorcycles, trains, aircraft, buses, and bicycles. Where Los Angeles is infamous for its automobile gridlock, commuting in New York is closely associated with the subway; in London and Tokyo and several European cities, "commuter" is automatically associated with rail passengers.[3] In the near future there may be another move away from the traditional "commute" with the introduction of flexible working. Some have suggested that many employees would be far more productive and live healthier, stress-free lives if the daily commute is removed completely.

Commuting has had a large impact on modern life. It has allowed cities to grow to sizes that were previously not practical, and it has led to the proliferation of suburbs. Many large cities or conurbations are surrounded by commuter belts, also known as metropolitan areas, commuter towns, dormitory towns, or bedroom communities. The prototypical commuter lives in one of these areas and travels daily to work or to school in the core city.

Most commuters travel at the same time of day, resulting in the morning and evening rush hours, with congestion on roads and public transport systems not designed or maintained well enough to cope with the peak demands. As an example, Interstate 405 located in Southern California is one of the busiest freeways in the United States. Commuters may sit up to two hours in traffic during rush hour. Construction work or collisions on the freeway distract and slow down commuters, contributing to even longer delays.

Cars carrying only one occupant use fuel and roads less efficiently than shared cars or public transport, and increase traffic congestion. Commuting by car is a major factor contributing to air pollution. Carpool lanes can help commuters reach their destinations more quickly, encourage people to socialize, and spend time together, while reducing air pollution.

Some governments and employers have introduced employee travel reduction programs that encourage such alternatives as car-pooling and telecommuting. Some are also carpooling using Internet sites to save money. Alternatives like personal rapid transit have also been proposed to reap the energy-efficiency benefits of a mass transit system while maintaining the speed and convenience of individual transport.

The major culprits from transportation sources are carbon monoxide (CO),[11][12] nitrogen oxides (NO and NOx),[13][14][15] volatile organic compounds,[12][13] sulfur dioxide,[12] and hydrocarbons.[12] (Hydrocarbons are the main components of petroleum fuels such as gasoline and diesel fuel.) These molecules react with sunlight, heat, ammonia, moisture, and other compounds to form the noxious vapours, ground level ozone, and particles that comprise smog.[12][13]

In the United States, the Census Bureau's American Community Survey (ACS) collects data on commuting times, allowing an analysis of average commute time by industry, location, and vehicle. According to the 2014 ACS, the average commute time for adults in the United States was 26.8 minutes. The occupations with the longest commutes were Construction and Mining (33.4 minutes), Computer Science and Math (31.8), and Business Operations Specialists (30.2), while those in the military had the shortest commute (21). In general, urban and suburban workers in the US have similar commute times (about 30 minutes), while rural workers have significantly shorter commutes (22.6 minutes). In the US, over 90% of workers commute by car, while about 5% commute by public transportation.[16]Statistical models[17] indicate that in addition to demographics and work duration, commute time is one of the most important determinants of discretionary time allocation by individuals.

New York City Subway
–
Opened in 1904, the New York City Subway is one of the worlds oldest public transit systems, one of the worlds most used metro systems, and the metro system with the most stations. It offers service 24 hours per day, every day of the year, the New York City Subway is the largest rapid transit system in the world by number of stations, with 472 stations in operation. Stations are located throughout the boroughs of Manhattan, Brooklyn, Queens, the Port Authority Trans-Hudson and the AirTrain JFK, in Manhattan and Queens respectively, accept the subways MetroCard but are not operated by the MTA and do not allow free transfers. Another mass transit service that is not operated by the MTA, the system is also one of the worlds longest. Overall, the system contains 236 miles of routes, translating into 665 miles of track. In 2015, the subway delivered over 1.76 billion rides, averaging approximately 5.7 million daily rides on weekdays and a combined 5.9 million rides each weekend. Of the systems 25 services,22 of them pass through Manhattan, the exceptions being the G train, the Franklin Avenue Shuttle, and the Rockaway Park Shuttle. Large portions of the subway outside Manhattan are elevated, on embankments, or in open cuts, in total, 40% of track is not underground despite the subway moniker. Many lines and stations have both express and local services and these lines have three or four tracks. Normally, the two are used for local trains, while the inner one or two are used for express trains. Stations served by express trains are typically major transfer points or destinations, alfred Ely Beach built the first demonstration for an underground transit system in New York City in 1869 and opened it in February 1870. The tunnel was never extended for political and financial reasons, although extensions had been planned to take the tunnel southward to The Battery, the Great Blizzard of 1888 helped demonstrate the benefits of an underground transportation system. A plan for the construction of the subway was approved in 1894, the first underground line of the subway opened on October 27,1904, almost 36 years after the opening of the first elevated line in New York City, which became the IRT Ninth Avenue Line. The fare was $0.05 and on the first day the trains carried over 150,000 passengers, the oldest structure still in use opened in 1885 as part of the BMT Lexington Avenue Line in Brooklyn and is now part of the BMT Jamaica Line. The oldest right-of-way, which is part of the BMT West End Line near Coney Island Creek, was in use in 1864 as a railroad called the Brooklyn, Bath. By the time the first subway opened, the lines had been consolidated into two privately owned systems, the Brooklyn Rapid Transit Company and the Interborough Rapid Transit Company, the city built most of the lines and leased them to the companies. This required it to be run at cost, necessitating fares up to double the five-cent fare popular at the time, in 1940, the city bought the two private systems. Some elevated lines ceased service immediately while others closed soon after, integration was slow, but several connections were built between the IND and BMT, these now operate as one division called the B Division

Rush hour
–
A rush hour is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest. Normally, this happens twice every weekday—once in the morning and once in the afternoon-evening, the term is often used for a period of peak congestion that may last for more than one hour. By analogy to vehicular traffic, the term Internet rush hour has been used to describe periods of peak data network usage, resulting in delays and slower delivery of data packets. The name is sometimes a misnomer, as the period often lasts more than one hour. Rush hour may be 6–10 am and 4–8 pm, Peak traffic periods may vary from city to city, from region to region, and seasonally. The frequency of public service is usually higher in the rush hour. The resulting crowding may force many passengers to stand, and others may be unable to board, if there is inadequate capacity, this can make public transport less attractive, leading to higher car use and partly shifting the congestion to roads. Transport demand management, such as road pricing or a charge, is designed to induce people to alter their travel timing to minimize congestion. Similarly, public transport fares may be higher during peak periods, season tickets or multi-ride tickets, sold at a discount, are commonly used in rush hours by commuters, and may or may not reflect rush hour fare differentials. Staggered hours have been promoted as a means of spreading demand across a time span, for example in Rush Hour. In Australia, Sydney, Brisbane and Melbourne and in New Zealand, Auckland and Christchurch are usually the most congested cities in the morning 6–9am, in Melbourne the Monash Freeway, which connects Melbournes suburban sprawl, to the city is usually heavily congested each morning and evening. In Perth, Mitchell Freeway, Kwinana Freeway and various arterial roads are usually congested between peak hours, making movement between suburbs and the city quite slow, efforts to minimise traffic congestion during peak hour vary on a state by state and city by city basis. In Melbourne, congestion is managed by means including, Inbound transit lanes on busy freeways which are limited to motorcycles, free travel on metropolitan trains before 7am. Passengers must exit the system at their station before 7am. Dedicated bus lanes on major city roads such as Hoddle Street. Introduction of dedicated lanes in the inner city area to encourage cyclists. Prohibition of parking along busy roads during peak periods to create an extra lane for traffic. In São Paulo, Brazil, each vehicle is assigned a day of the week in which it cannot travel the roads during rush hour

Shinjuku Station
–
Shinjuku Station is a major railway station in Shinjuku and Shibuya wards in Tokyo, Japan. The station itself has 36 platforms, including an arcade, above ground arcade. There are well over 200 exits, another 17 platforms can be accessed through hallways to 5 directly connected stations without surfacing outside. These consist of eight island platforms on a north-south axis. The JR section alone handles an average of 1.5 million passengers a day, the terminus for the private Odakyu Odawara Line is parallel to the JR platforms on the west side, and handles an average of 490,000 passengers daily. This is a commuter route stretching southwest through the suburbs and out towards the coastal city of Odawara. The ten platforms are built on two levels beneath the Odakyu department store, three express service tracks on the level and two tracks on the level below. Each track has platforms on both sides in order to separate boarding and alighting passengers. Chest-high platform screen doors were added to platforms 4 and 5 in September 2012, the Keio Line concourse is located to the west of the Odakyu line concourse, two floors below ground level under Keio department store. It consists of three platforms stretching north to south, approximately 720,000 passengers use this section daily, which makes it the busiest amongst the non-JR Group railways of Japan. This suburban commuter line links Shinjuku to the city of Hachiōji to the west, chest-high platform edge doors were introduced on the Keio Line platforms in March 2014. The doors are different colours for each platform, the doors on platform 2 are green. The concourse is managed by Keio Corporation but is in a location to the main Keio platforms. Further south are the two north-to-south Toei Ōedo subway line platforms, Tokyo Metros two Marunouchi Line underground platforms stretch east-west to the north of the JR and Odakyu facilities, directly below the Metro Promenade underground mall. Many department stores and shopping malls are built directly into the station, the Metro Promenade in turn connects to Shinjuku Subnade, another underground shopping mall, which leads onto Seibu Railways Seibu-Shinjuku station. On April 4,2016, the new bus terminal and commercial facilities nearby south exit, named Busta Shinjuku, considerable numbers of the coaches and the airport buses depart from this new terminal. The figures below are the number of passengers entering and exiting each day released by each train operator. The figure for JR East only includes entering passengers, the passenger figures for the JR East station in previous years are as shown below

Tokyo
–
Tokyo, officially Tokyo Metropolis, is the capital of Japan and one of its 47 prefectures. The Greater Tokyo Area is the most populous area in the world. It is the seat of the Emperor of Japan and the Japanese government, Tokyo is in the Kantō region on the southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara Islands. Formerly known as Edo, it has been the de facto seat of government since 1603 when Shogun Tokugawa Ieyasu made the city his headquarters. It officially became the capital after Emperor Meiji moved his seat to the city from the old capital of Kyoto in 1868, Tokyo Metropolis was formed in 1943 from the merger of the former Tokyo Prefecture and the city of Tokyo. The Tokyo metropolitan government administers the 23 Special Wards of Tokyo, the metropolitan government also administers 39 municipalities in the western part of the prefecture and the two outlying island chains. The population of the wards is over 9 million people. The prefecture is part of the worlds most populous metropolitan area with upwards of 37.8 million people, the city hosts 51 of the Fortune Global 500 companies, the highest number of any city in the world. Tokyo ranked third in the International Financial Centres Development IndexEdit, the city is also home to various television networks such as Fuji TV, Tokyo MX, TV Tokyo, TV Asahi, Nippon Television, NHK and the Tokyo Broadcasting System. Tokyo ranked first in the Global Economic Power Index and fourth in the Global Cities Index. The city is considered a world city – as listed by the GaWCs 2008 inventory – and in 2014. In 2015, Tokyo was named the Most Liveable City in the world by the magazine Monocle, the Michelin Guide has awarded Tokyo by far the most Michelin stars of any city in the world. Tokyo ranked first in the world in the Safe Cities Index, the 2016 edition of QS Best Student Cities ranked Tokyo as the 3rd-best city in the world to be a university student. Tokyo hosted the 1964 Summer Olympics, the 1979 G-7 summit, the 1986 G-7 summit, and the 1993 G-7 summit, and will host the 2020 Summer Olympics, Tokyo was originally known as Edo, which means estuary. During the early Meiji period, the city was also called Tōkei, some surviving official English documents use the spelling Tokei. However, this pronunciation is now obsolete, the name Tokyo was first suggested in 1813 in the book Kondō Hisaku, written by Satō Nobuhiro. When Ōkubo Toshimichi proposed the renaming to the government during the Meiji Restoration, according to Oda Kanshi, Tokyo was originally a small fishing village named Edo, in what was formerly part of the old Musashi Province. Edo was first fortified by the Edo clan, in the twelfth century

Traffic congestion
–
Traffic congestion is a condition on transport networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queueing. The most common example is the use of roads by vehicles. When traffic demand is great enough that the interaction between vehicles slows the speed of the stream, this results in some congestion. As demand approaches the capacity of a road, extreme traffic congestion sets in, when vehicles are fully stopped for periods of time, this is colloquially known as a traffic jam or traffic snarl-up. Traffic congestion can lead to becoming frustrated and engaging in road rage. Mathematically, congestion is usually looked at as the number of vehicles that pass through a point in a window of time, Congestion flow lends itself to principles of fluid dynamics. Traffic congestion occurs when a volume of traffic or modal split generates demand for greater than the available street capacity. About half of U. S. traffic congestion is recurring, Traffic research still cannot fully predict under which conditions a traffic jam may suddenly occur. It has been found that individual incidents may cause ripple effects which then spread out and create a traffic jam when, otherwise. Some traffic engineers have attempted to apply the rules of fluid dynamics to traffic flow, Traffic scientists liken such a situation to the sudden freezing of supercooled fluid. However, unlike a fluid, traffic flow is affected by signals or other events at junctions that periodically affect the smooth flow of traffic. Alternative mathematical theories exist, such as Boris Kerners three-phase traffic theory, because of the poor correlation of theoretical models to actual observed traffic flows, transportation planners and highway engineers attempt to forecast traffic flow using empirical models. These models are typically calibrated by measuring actual traffic flows on the links in the network. That discovery enabled the team to solve traffic-jam equations that were first theorized in the 1950s, congested roads can be seen as an example of the tragedy of the commons. Privatization of highways and road pricing have both proposed as measures that may reduce congestion through economic incentives and disincentives. Congestion can also happen due to non-recurring highway incidents, such as a crash or roadworks, economist Anthony Downs argues that rush hour traffic congestion is inevitable because of the benefits of having a relatively standard work day. In a capitalist economy, goods can be allocated either by pricing or by queueing and they determined that the number of vehicle-kilometers traveled increases in direct proportion to the available lane-kilometers of roadways. The implication is that new roads and widening existing ones only results in additional traffic that continues to rise until peak congestion returns to the previous level

Maryland
–
The states largest city is Baltimore, and its capital is Annapolis. Among its occasional nicknames are Old Line State, the Free State, the state is named after Henrietta Maria of France, the wife of Charles I of England. George Calvert was the first Lord of Baltimore and the first English proprietor of the colonial grant. Maryland was the state to ratify the United States Constitution. Maryland is one of the smallest U. S. states in terms of area, as well as one of the most densely populated, Maryland has an area of 12,406.68 square miles and is comparable in overall area with Belgium. It is the 42nd largest and 9th smallest state and is closest in size to the state of Hawaii, the next largest state, its neighbor West Virginia, is almost twice the size of Maryland. Maryland possesses a variety of topography within its borders, contributing to its nickname America in Miniature. The mid-portion of this border is interrupted by Washington, D. C. which sits on land that was part of Montgomery and Prince Georges counties and including the town of Georgetown. This land was ceded to the United States Federal Government in 1790 to form the District of Columbia, the Chesapeake Bay nearly bisects the state and the counties east of the bay are known collectively as the Eastern Shore. Close to the town of Hancock, in western Maryland, about two-thirds of the way across the state. This geographical curiosity makes Maryland the narrowest state, bordered by the Mason–Dixon line to the north, portions of Maryland are included in various official and unofficial geographic regions. Much of the Baltimore–Washington corridor lies just south of the Piedmont in the Coastal Plain, earthquakes in Maryland are infrequent and small due to the states distance from seismic/earthquake zones. The M5.8 Virginia earthquake in 2011 was felt moderately throughout Maryland, buildings in the state are not well-designed for earthquakes and can suffer damage easily. The lack of any glacial history accounts for the scarcity of Marylands natural lakes, laurel Oxbow Lake is an over one-hundred-year-old 55-acre natural lake two miles north of Maryland City and adjacent to Russett. Chews Lake is a natural lake two miles south-southeast of Upper Marlboro. There are numerous lakes, the largest of them being the Deep Creek Lake. Maryland has shale formations containing natural gas, where fracking is theoretically possible, as is typical of states on the East Coast, Marylands plant life is abundant and healthy. Middle Atlantic coastal forests, typical of the southeastern Atlantic coastal plain, grow around Chesapeake Bay, moving west, a mixture of Northeastern coastal forests and Southeastern mixed forests cover the central part of the state

Travel
–
Travel can also include relatively short stays between successive movements. The origin of the travel is most likely lost to history. The term travel may originate from the Old French word travail, according to the Merriam Webster dictionary, the first known use of the word travel was in the 14th century. It also states that the word comes from Middle English travailen, travelen, in English we still occasionally use the words travail, which means struggle. According to Simon Winchester in his book The Best Travelers Tales and this link may reflect the extreme difficulty of travel in ancient times. Today, travel may or may not be much easier depending upon the destination you choose, how you plan to get there, theres a big difference between simply being a tourist and being a true world traveler, notes travel writer Michael Kasum. This is, however, a distinction as academic work on the cultures. Travel may occur by human-powered transport such as walking or bicycling, or with vehicles, such as transport, automobiles, trains. In some countries, non-local internal travel may require a passport, while international travel typically requires a passport. A trip may also be part of a round-trip, which is a type of travel whereby a person moves from one location to another. Once difficult, slow and dangerous, travel has tended to become easier, quicker, the evolution of technology such as horse tack and bullet trains has contributed to this trend. While travel in the Middle Ages offered hardships and challenges, it loomed large in the economy, pilgrimages involved streams of travellers both locally and internationally. Travel by water provided more comfort and speed than land-travel - at least until the advent of a network of railways in the 19th century. Airships and airplanes usurped much of the role of surface travel in the twentieth century. Authorities emphasize the importance of taking precautions to ensure travel safety, when traveling abroad, the odds favor a safe and incident-free trip, however, travelers can be subject to difficulties, crime and violence. Many countries do not recognize drivers licenses from other countries, however most countries accept international driving permits, automobile insurance policies issued in ones own country are often invalid in foreign countries, and it is often a requirement to obtain temporary auto insurance valid in the country being visited. It is also advisable to become oriented with the driving-rules and -regulations of destination countries, wearing a seat belt is highly advisable for safety reasons, many countries have penalties for violating seatbelt laws

Industrial Revolution
–
The Industrial Revolution was the transition to new manufacturing processes in the period from about 1760 to sometime between 1820 and 1840. The Industrial Revolution began in Great Britain and most of the important technological innovations were British, aided by these legal and cultural foundations, an entrepreneurial spirit and consumer revolution drove industrialisation in Britain, which would be emulated in countries around the world. A change in marrying patterns to getting married later made able to accumulate more human capital during their youth. The Industrial Revolution marks a turning point in history, almost every aspect of daily life was influenced in some way. In particular, average income and population began to exhibit unprecedented sustained growth, mechanised textile production spread from Great Britain to continental Europe in the early 19th century, with important centres of textiles, iron and coal emerging in Belgium, and later in France. Since then industrialisation has spread throughout much of the world, the precise start and end of the Industrial Revolution is still debated among historians, as is the pace of economic and social changes. Economic historians are in agreement that the onset of the Industrial Revolution is the most important event in the history of humanity since the domestication of animals and plants. The term Industrial Revolution applied to change was becoming more common by the late 1830s. Friedrich Engels in The Condition of the Working Class in England in 1844 spoke of an industrial revolution, however, although Engels wrote in the 1840s, his book was not translated into English until the late 1800s, and his expression did not enter everyday language until then. Credit for popularising the term may be given to Arnold Toynbee, some historians, such as John Clapham and Nicholas Crafts, have argued that the economic and social changes occurred gradually and the term revolution is a misnomer. This is still a subject of debate among some historians, the commencement of the Industrial Revolution is closely linked to a small number of innovations, beginning in the second half of the 18th century. By the 1830s the following gains had been made in important technologies, Textiles – mechanised cotton spinning powered by steam or water greatly increased the output of a worker, the power loom increased the output of a worker by a factor of over 40. The cotton gin increased productivity of removing seed from cotton by a factor of 50, large gains in productivity also occurred in spinning and weaving of wool and linen, but they were not as great as in cotton. Steam power – the efficiency of steam engines increased so that they used between one-fifth and one-tenth as much fuel, the adaptation of stationary steam engines to rotary motion made them suitable for industrial uses. The high pressure engine had a power to weight ratio. Steam power underwent an expansion after 1800. Iron making – the substitution of coke for charcoal greatly lowered the fuel cost for pig iron, using coke also allowed larger blast furnaces, resulting in economies of scale. The cast iron blowing cylinder was first used in 1760 and it was later improved by making it double acting, which allowed higher furnace temperatures

Public transport
–
Public transport modes include city buses, trolleybuses, trams and passenger trains, rapid transit and ferries. Public transport between cities is dominated by airlines, coaches, and intercity rail, high-speed rail networks are being developed in many parts of the world. Most public transport runs to a timetable, with the most frequent services running to a headway. Share taxis offer services in many parts of the world. Paratransit is sometimes used in areas of low demand and for people who need a door-to-door service, there are distinct differences in urban public transit between Asia, North America, and Europe. In Asia, mass transit operations are run by profit-driven privately owned and publicly traded mass transit. In North America, mass transit operations are run by municipal transit authorities. In Europe, mass transit operations are run by both state-owned and private companies. Public transport services can be profit-driven by use of pay-by-the-distance fares or funded by government subsidies in which flat rate fares are charged to each passenger. Services can be profitable through high ridership numbers and high farebox recovery ratios, or can be regulated. Fully subsidized, zero-fare services operate in some towns and cities, for geographical, historical and economic reasons, there are differences internationally regarding use and extent of public transport. It has 3,400 members from 92 countries, conveyances designed for public hire are as old as the first ferries, and the earliest public transport was water transport, on land people walked or rode an animal. Ferries appear in Greek mythology—corpses in ancient Greece were buried with a coin underneath their tongue to pay the ferryman Charon to take them to Hades, the omnibus was introduced to London in July 1829. The first passenger railway opened in 1806, it ran between Swansea and Mumbles in southwest Wales in the United Kingdom. In 1825 George Stephenson built the Locomotion for the Stockton and Darlington Railway in northeast England, the usability of different types of public transport, and its overall appeal, can be measured by seven criteria, although they overlap somewhat. These are speed, comfort, safety, cost, proximity, speed is calculated from total journey time including transfers. Proximity means how far passengers have to walk or otherwise travel before they can begin the public transport leg of their journey, timeliness is how long they have to wait for the vehicle. Directness records how far a journey using public transport deviates from the shortest route, an airline provides scheduled service with aircraft between airports

Mode of transport
–
Mode of transport is a term used to distinguish substantially different ways to perform. The most dominant modes of transport are air, water, and land transport, other modes also exist, including pipelines, cable transport, and space transport. Human-powered transport and animal-powered transport are sometimes regarded as their own mode, in general, transportation is used for the movement of people, animals, and other things. Each mode of transport has a different technological solution. Each mode has its own infrastructure, vehicles, and operations, each mode also has separate subsystems. A fixed-wing aircraft, typically airplane, is a flight vehicle. Fixed-wing aircraft ranges from small trainers and recreational aircraft to large airliners, for short distances or in places without runways, helicopters can be practical. Air transport is the second fastest method of transport, after space travel and this celerity comes with higher cost and energy use, and aviations impacts to the environment and particularly the global climate require consideration when comparing modes of transportation. U. S. airlines alone burned about 16.2 billion gallons of fuel during the months between October 2013 and September 2014. WHO estimates that globally as many as 500,000 people at a time are on planes, land transport covers all land-based transportation systems that provide for the movement of people, goods and services. Land transport plays a role in linking communities to each other. The rails are anchored perpendicular to railroad train consists of one or more connected vehicles that run on the rails, propulsion is commonly provided by a locomotive, that hauls a series of unpowered cars, that can carry passengers or freight. The locomotive can be powered by steam, diesel or by electricity supplied by trackside systems, alternatively, some or all the cars can be powered, known as a multiple unit. Also, a train can be powered by horses, cables, gravity, pneumatics, railed vehicles move with much less friction than rubber tires on paved roads, making trains more energy efficient, though not as efficient as ships. Intercity trains are long-haul services connecting cities, modern high-speed rail is capable of speeds up to 430 km/h, Freight trains traditionally used box cars, requiring manual loading and unloading of the cargo. Since the 1960s, container trains have become the dominant solution for general freight, a road is an identifiable route of travel, usually surfaced with gravel, asphalt or concrete, and supporting land passage by foot or by a number of vehicles. The most common vehicle in the developed world is the automobile. As of 2002, there were 591 million automobiles worldwide, other users of roads include motorcars, motorcycles, buses, trucks, bicycles and pedestrians, and special provisions are sometimes made for each of these
